Background technique
Cardboard box printing grooving machine is provided with many axles, roller, these beaming rollers need be by certain direction rotation when work, axle that wherein has or roller are except rotating by certain orientation, do not need to carry out the adjustment and the change of position, but axle that has or roller be except by the certain position direction rotation, also needs the thickness according to cardboard, the concentration that goes up China ink, the characteristics such as uniformity that go up China ink to carry out the adjustment of position.Axle on the cardboard box printing grooving machine or roller rotation, basically be that transmission by train realizes, and the position of each member is constant in the train, when the axle of needs adjustment or after roller adjusting, the center that rotatablely moves of the gear on the axle or the center that rotatablely moves of roller and this or the roller produces and is offset, gear will pass to axle or roller with rotatablely moving, and in existing grooving-cutting machine is to adopt sliding cross coupling.Sliding cross coupling exists processing difficulties, and the form and position tolerance during making is difficult to guarantee, influences assembly quality, the back is installed produces bigger noise, and bearing capacity is limited.
Summary of the invention
The purpose of this utility model provides and a kind ofly can improve assembly precision, stable working is reliable, bearing capacity is higher oldham coupling.
The purpose of this utility model is achieved in that it is the slide block that comprises between trough of belt wheel rim gear, shifting block, gear and the shifting block; Also comprise the symmetrical chute of establishing on the tooth slide block outer rim, first, second flange servo-actuated bearing of adorning on the gear; The the 3rd, the 4th flange servo-actuated bearing of adorning on the shifting block, the roller face of first, second flange servo-actuated bearing and the 3rd, the 4th flange servo-actuated bearing places symmetrical chute respectively.
The utility model can guarantee assembly quality because processing is easier to, and can not produce bigger noise after the installation, and bearing capacity is higher, also has the reliable advantage of stable working.
